1. Newtons 1st Law Object wants to be in it’s natural resting place
-For an object to move a force
must be acting on the object
Once in motion no push or
pull is needed to keep it moving
-Force is needed only to change
motion

2. INERTIA NEWTONS 1st LAW: An object at rest will remain at rest, an
Whether at rest or moving
every object in motion
resists change of motion
NEWTONS 1st LAW:
An object at rest will remain at rest, an
object that is moving at constant
velocity will continue moving unless
acted upon by an outside force

3. Mass vs. Weight SI Unit for: MASS = Kilogram (kg)
Mass is the quantity of matter in an object
Weight is gravitational force exerted on an object by nearest most massive body (EARTH)
SI Unit for: MASS = Kilogram (kg)
there are 1,000 grams (g) in a kilogram
person = about 45 kg
small car = about 1,000 kg
mass of a nickel = about 5 g
Unit for: WEIGHT = newton (N)
1 kg brick weighs about 9.8 (N)
WHERE HAVE WE SEEN THIS BEFORE 9.8 BEFORE?

4. 9 INERTIA examples
Draw 9 examples of where inertia occurs in the real world
Explain briefly how inertia occurs there, don’t just tell me the situation
DO NOT use my examples
